BOSTON (AP)  Japan’s prime minister has arrived in the U.S. for a closely watched visit beginning with a stop at Boston’s John F. Kennedy Presidential Library and a dinner hosted by Secretary of State John Kerry.

Shinzo Abe (shin-zoh ah-bay) arrived Sunday. He speaks at Harvard’s Kennedy School of Government on Monday before heading to Washington on Tuesday, where he’ll be the first Japanese leader to address a joint session of Congress.

Abe will also make stops in Los Angeles and San Francisco.

Protesters are calling on Abe to apologize for World War II-era crimes, including sexual slavery in Korea. Twenty-five U.S. lawmakers urged him “to formally reaffirm and validate” apologies made by his predecessors for Japanese wartime aggression.

Trade and new security arrangements between the two countries are top issues.
